There's a problem with importing nested scopes in
shell mode in IDLE in 2.1.  Cut and paste the code
to a text file with

from __future__ import nested_scopes

at the top of the file.  Save as danny.py or whatever
and import e.g.

from danny import diff

This will cause nested scopes to kick in and allow you
to use diff interactively.
